LEMUEL'-BANNISTER, OF PHILADELPHIA, PENNSYLVANIA.

GRATE.

SPECIFICATION farming .To all whom t't may concern: Be it known that I, LEMUEI. BANNISTER, of the city and county ot' Philadelphia, and State ot' Pennsylvania, have invented Improvements in Grates, o t which the following is a specification. V

My invention isa grate constructed, as fully described hereinafter, so as to facilitate the removal ot' the contents of the tire-pot,'avoid obstructing the ash-pit, and with bars constructed to avoid the loss resulting from the ordinary constructions.

In the drawings, Figure l is a longitudinal section of a grate showing my improvements, and Fig. 2 is a plan View.

In ordinary grates provided with rockingbars it is commonto dump the tire or dis` charge the contents of the tire-pot by dropping the front ends of one or more. bars. This is` objectionable, as thedropped bar obstructs access to the ashpit,aud when embedded in the ashes is difficult to elevate. -I avoid these objections, first, by so constructing one of the bars that it may be turned to such a position independently ,of the others as to open a passage for the discharge ot the contents of the tire-pot, and, secondly, by placing such bar at the rear ofthe grate, therebyavoiding'any obstructing ofthe ash-pit'at the front.

, ternating with those ot' the next bar.

Thus in the grate illustrated, A is the frame; B, the rockingbars, which have journals a, sidengers, b, and are rocked by any suitable appliances; and C is the dumping-bar arranged at the rear ot' the grate, having journais a, and with fingers at one side only, al-

The journals of the bar G are preferably arranged eccentrically nearest the rear side, so that when the bar is turned to drop the tiugers the bar will be carried away from the next bar and leave a wide opening for the passage of the tire or ashes. As the bar G is vat the rear, it

in no way interferes with the free removal of the contents ot' the ash-pit, or with access thereto, and it is, moreover, much easier to push the ashes back to the rear opening than to drag them to the front.

til the tingers are vertical.

part of Letters Patent No. 272,514, dated February 20, 1883. Application inea December 1s, ieee. (No modem Any suitable device may be employed ,.to turn the bar() and hold it in its horizontal position. I have shown ant-lever, F, which, when in the position shown in dotted lilies, is beneath the end finger of the bar and supports the latter, but when turned to the position shown in full lines permits the bar to turn un- This lever F may be operated by a lever, G, at the front of the grate, and a connecting-rod, H, as shown.

One or more fingers of a rocking grate-bar will sometimes burn away or become warped by heat, so that the entire har must be discarded. I avoid this by making each bar with a series ot sockets, w, adapted to receive the ends ot'deta'chable ngers, any one otl which may be removed when injured and a new one substituted therefor.

I am aware that grates have been made with independent bars,'any one of which may be turned to bring the ngers to a vertical position. I do not claim this, my invention relating to that class of grat-es in which the raking is done bythe simultaneous movement ot' the connected bars.

I claimel. The combination, with the rocking tingered bars ot' a grate, connected as set forth,

ot' an independent bar, (.l, having fingers alterhating with those ot' the next bar, and appliauces whereby said bar C may be turned to drop the lingers, substantially as described.

2. The combination of bars B, connected as set forth, the rocking bar G audlever F, and

operating appliances, substantially as de scribed.

3. A rocking grate-bar with a body having a series ot' sockets at each side, and detachable lateral fingers with inner ends adapted to said sockets, substantially as described.`

Iutestimony whereofl have signed my name toY -this specilication in the presence ot' two subscribing witnesses.
